You are helping other dreamers by sharing what you submitted, whether or not you hired a lawyer, what your timeline is, answering their questions, bouncing around ideas, and eventually what questions were asked during your interview and what pieces of evidence you brought.

You are not helping fellow dreamers by accusing another fellow dreamer of wishing you the worst or telling them you're wrong when you haven't even been proven right.
